Description

[Detailed description of the invention] This invention measures the weight of each vehicle entering the parking lot in mechanical parking facilities such as vertical circulation type, multilayer circulation type, or horizontal circulation type, and prevents vehicles exceeding the preset weight limit from parking. The invention relates to a parking control device in a mechanical parking facility whose purpose is to prevent parking.

Conventionally, for example, in vertical circulation parking equipment, a load converter that can detect the load and convert it into an electrical signal has been inserted in the support beam of the structure that supports the upper and lower sprockets, the chain, the cage, the drive device, etc. Therefore, the total load applied to the building was constantly monitored to prevent damage to the Cheno or the building itself due to overload.

However, in the above-mentioned system, no measures have been taken to limit the weight of individual vehicles entering the warehouse.For example, vehicles that are permitted to enter the warehouse due to vehicle length, vehicle width, and vehicle height may not carry tools, equipment, cylinders, etc. Even the loaded items will get into the cage, and in this case, if the weight of the vehicle including the loaded items increases, the cage itself will not be able to withstand the load and will become distorted, no matter how small the total load on the cheno and the structure. This could lead to damage and even lead to a major accident involving the entire parking facility.

In view of the above-mentioned current situation, the present invention includes a weight detection unit that detects the weight of a vehicle before entering or exiting a parking facility, and an excess determination unit that receives information from the weight detection unit and compares it with a preset weight limit value. and a vehicle entry prevention member provided in a vehicle path leading to the parking facility operates to prevent the vehicle from entering only when the determination means section issues an excess signal;
The present invention relates to a parking control device for a mechanical parking facility, which aims to eliminate various problems caused by excessive weight on individual parking cages and all parking facilities in the parking facility.

To explain in detail the embodiment shown in the figure, Fig. 1 is a side view of a vertical circulation type 1 parking facility employing the warehousing control device of the present invention. A pair of provided sprocket wheels 3.4 are connected by an endless chain 5, and the cage 1 is pivotally suspended from the endless chain 5 at equal intervals, and is circulated by a drive device 6 provided at the lower part of the upper sprocket wheel 3. The vehicle 8 is driven into and out of the cage 1 at an entry/exit lower formed at the lowest part of the building 2.

9 is a vehicle weight detection unit installed in the front of the loading/unloading lower;
It consists of the following composition.

First and second to fifth load converters capable of detecting the applied load and converting it into an electrical signal are installed at four locations in the center of the floor 11a of the circular pit 11 dug in the ground floor 10 and in the circumference of the anvil 11a. 12. Install 13, 14, 15. It is supported by a bearing 18 provided therein.

Further, the turntable 17 has the center shaft 17 on the lower surface.
A circular strip plate 19 centered at a is attached, and the second to
The support rollers 20 supported on the upper surface of each of the five load converters 13 to 16 are movably engaged with the strip plate 19, thereby maintaining the horizontal position at all times.

Reference numeral 21 denotes a forward/reverse motor with a reducer and a brake installed in a small pit 22 provided in communication with the side of the pit 11, which drives the circumferential surface of the friction roller 23 fixed to the shaft end of the turntable 17. It is press-fitted to the friction peripheral surface 17b so as to be freely movable, and the turntable 17 is rotated by the drive of the forward/reverse rotation motor 21.

Reference numeral 24 indicates a limit switch fixed to the wall surface 11b of the pit 11, and reference numeral 25 indicates two sliding/sliding forces installed vertically on the lower surface of the turntable 17 at symmetrical positions with respect to the central axis 17a. When the limit switch 24 is engaged with either one of the strikers 25, the limit switch 24 generates a signal to stop the drive of the forward/reverse motor 21.

Reference numeral 26 denotes an excess weight determination means installed near the loading/unloading lower, and a support 27 is installed on the ground floor 10 on the right side toward the loading/unloading lower.
is erected, and a determining means main body 28 is fixed to the upper end of the support column 27.

FIG. 4 is a block diagram schematically showing a control circuit built into the discriminating means main body 28. As shown in FIG.

In Figure 4, 101, 102, 103, 104, 1
05 are the detected loads W and W2 from the first to fifth load converters 12 to 16, respectively. W3. W4. A detection load register that converts the electrical signal representing W5 into a digital display.
The outputs of the registers 101 to 105 serve as inputs to an adder 106, and the output of the adder 106 serves as one input to a comparator 107.

Reference numeral 108 denotes a limit weight setting device that can set a limit weight value Wo indicating the limit of the load that can be loaded on one cage 1, and its output is passed through a limit weight value register 109 to the other side of the comparator 107. This is the input.

The comparator 107 receives the input from the adder 106, that is, the total detected load W(-
W1+W2+W3+W4+W5) and the register 109
Compare the limit weight value Wo from W<Wo or W≧
It is designed to discriminate Wo and generate respective discrimination signals.

Reference numeral 29 denotes an electronic display board attached to the front surface of the discriminating means body 28 as a storage prohibition display/warning means, and the comparator 107
It is activated only when a signal indicating W≧Wo is received from the vehicle, and displays, for example, a light that says ``Your vehicle cannot enter the warehouse because it exceeds the weight limit.''

Incidentally, an alarm (not shown) which operates in conjunction with the lighting display may be provided as necessary.

Reference numeral 30 denotes a vehicle entry prevention means provided between the storage entry/exit lower and the weight detection section 9, which supports the upper wall of the recess 31 drilled in the ground floor 10 and rotates in the vertical direction. The air cylinder 33 has its lower end swingably installed in the recess 31 and the tip of the rod is pivotally connected to the central lower surface of the blocking plate 32.The blocking plate 32 is normally The upper surface is held flush with the ground floor 10, and W≧W is determined from the comparator 107.

Only when this signal is received, the rod is extended by the actuation of the air cylinder 33, rotates in the -L direction and protrudes above the ground, and completely prevents the vehicle 8 from entering the storage/exit lower.

Reference numeral 34 denotes an opening/closing door provided at the entrance/exit lower door, which is closed when the cage 1 is being circulated and when the entire parking facility is not in use, such as at night, and is opened only when the vehicle 8 enters and exits.

Next, the effect will be explained.

It is now assumed that an empty cage 1 is waiting at a predetermined position in the warehouse [7].

Then, the vehicle 8 that is about to enter the warehouse approaches the entry/exit lower,
When you get on the turntable 17-F and stop, the first to
5 load converters 12-16 each detect the applied load, convert it into an electric signal, and input it to each detected load register 101-105 of the determining means main body 2B.

The detected load values Wl, W2 . from these detected load registers 101 to 105 are detected. W3. W4. W5 is added in adder 106, and the total detected load value W is input to comparator 107.

The comparator 107 receives the aforementioned limit weight value W. and the total load value W, and if W<Wo, a signal of "less than the limit weight" is generated, and if W≧WO, a signal of "over the limit weight" is generated.

When the comparator 107 generates a signal indicating that the weight is below the limit weight, the forward/reverse motor 21 is driven to rotate the turntable 17 by 180 degrees, and the vehicle 8 moves backward into the cage 1 from the loading/unloading lower. It is now possible to board.

Conversely, if the comparator 107 generates a signal indicating that the weight exceeds the limit, the forward/reverse motor 21 is rendered inoperable, and the vehicle entry blocking means 30 closes the blocking plate by operating the air cylinder 33. 32 is rotated and projected upward as shown by the two-dot chain line in FIG. 2, the vehicle 8 is completely prevented from entering the warehouse in the lower direction.

Furthermore, at the same time, the electric display board 29 lights up, so
The driver of the vehicle 8 learns that he cannot enter the warehouse because the weight exceeds the weight limit, and moves the vehicle 8 away from the turntable 17.

In addition, in the first embodiment described above, the vehicle entry prevention means 30
Instead, a vehicle entry prevention means 300 as shown in FIG.
This can also be done using .

That is, as a second embodiment, the vehicle entry blocking means 300 is configured to sandwich a vehicle entry path between a weight detection section 900 having the same configuration as the weight detection section 9 and a warehouse loading/unloading lower 00 (not shown), and to prevent the vehicle from entering in the direction of vehicle entry. A column 301 and a frame 302 are erected on the ground floor 303 at a distance perpendicular to the column.
At the upper end of 1, a spring (
The rotating arm 304 is rotatable in a vertical plane perpendicular to the direction of vehicle entry, and is biased downward by its own weight.

Further, a rope winding/rewinding drum 306 is installed on the pedestal 302-H, and the rope 3 led out from the drum 306 is
07 is engaged with the tip of the rotating arm 304.

The vehicle entry prevention means 300 is normally in a state where the rope 307 is unwound and stretched on the ground floor 303, as shown by the two-dot chain line in FIG. A comparator (not shown) that can enter the port (700) and corresponds to the comparator 107 in the first embodiment.
In response to this, the rope winding/rewinding drum 306 winds up the rope 307, and the rope 307 is lifted from the ground floor 303 along with the rotating arm 304 as shown by the solid line in FIG. It is raised to a predetermined height position to prevent vehicles from entering in the direction of the entrance/exit (700).

As shown in FIG. 6, a fan-shaped foldable display board 308 is provided between the support column 301 and the rotating arm 304, and the display board 308 reads ``Your vehicle cannot enter the warehouse because it exceeds the weight limit.'' If the above phrase is written, the driver of the vehicle can visually see the display board 308 during the rope winding, and in this case, the electronic display board 29 in the first embodiment is unnecessary.

Furthermore, in the first embodiment, an opening/closing door 34 may be used instead of the vehicle entry blocking means 30.

In addition, as the means for preventing vehicle entry, an opening/closing gate such as one used at a railroad crossing can also be implemented.

Furthermore, in a mechanical parking facility that does not include a turntable, the turntable may simply be a fixed table on which a vehicle can be placed.

As detailed above, when using the device of the present invention, the weight of each vehicle entering the garage is measured by the weight detection unit before the entrance to the garage, and the weight can be loaded onto the cage using the excess weight determination means. It determines whether the weight is larger or smaller than the preset maximum weight, and if the weight is smaller, the vehicle is allowed to enter the cage through the entry/exit entrance, but if it is larger, the vehicle is operated with an electronic display board or alarm. The cage and/or the entire parking facility were damaged due to a vehicle exceeding the weight limit mistakenly entering the cage by notifying the person that the vehicle exceeded the weight limit and activating the vehicle entry prevention means to forcibly prevent the vehicle from entering the cage. The risk of failure and accidents can be completely eliminated.
